The AC254-045-C-ML is a multiplet lens, specifically an achromatic doublet, sourced from Thorlabs. This lens boasts a 25.4 mm diameter and an effective focal length (EFL) of 45mm, making it suitable for a wide range of applications within the 1050-1700nm spectral range.
The lens is composed of two distinct materials: N-LAK22 and N-SF6HT, both from Schott. These materials are chosen for their specific optical properties, contributing to the lens' overall performance. The lens is coated with THo AC1050-1700-C on both the front and back surfaces, further enhancing its capabilities within the specified spectral range.
The lens geometry is intricately designed, with an edge thickness of 7.7mm and a central thickness of 9.6mm for the first center and 1.8mm for the second. The radii of curvature are r1=22.9mm, r2=-23.7mm, and r3=900mm. The lens' base shape is circular, and it features an inner radius of 0mm and an outer radius of 0mm.
